JJ Wetherholt, SS, Cardinals: MVP-caliber 2025 and early MLB impact potential

Wetherholt (pictured above) had a breakout season in 2025, cementing himself as one of baseball’s elite young bats and a strong contender to factor into 2026 Rookie of the Year discussions. Across Double-A Springfield and Triple-A Memphis, he slashed .306/.421/.510 with a .931 OPS, contributing 17 home runs, 59 RBIs, and 23 stolen bases in 109 games while showing excellent on-base skills and speed. He also earned organizational and league honors, being named the Cardinals’ Minor League Player of the Year and the Texas League MVP — rare distinctions for a player his age.

Wetherholt’s 2025 performance combined mature plate discipline with power growth — the kind of balanced profile that has evaluators projecting him toward a significant role in St. Louis in 2026. With versatility shown across the infield and already excelling at Triple-A, he is poised to push for an Opening Day roster spot and could rack up counting stats early in his big-league tenure. Recent coverage suggests he’s expected to play a key offensive role for the Cardinals in 2026, and if he delivers anywhere near his minor-league production at the MLB level, a Rookie of the Year campaign isn’t out of the question.

Kevin McGonigle, 2B/SS, Tigers: Elite contact, AFL MVP, and 2026 ROY upside

McGonigle put together one of the most analytically impressive offensive seasons among all 2025 minor leaguers, making him another strong candidate for a 2026 Rookie of the Year push. Though his season was shortened due to injury, he slashed .305/.408/.583 with 19 home runs, 80 RBIs, and outstanding plate discipline, evidenced by a 182 wRC+ — the highest among over 1,000 qualified minor leaguers.

McGonigle capped his campaign with a standout showing in the Arizona Fall League, where he was named AFL MVP after slashing .362/.500/.710 over 88 plate appearances, showcasing both power and on-base ability against high-end pitching. Even in a crowded Tigers infield picture, Detroit’s offseason planning indicates he’s firmly in the mix for a 2026 big-league opportunity, with flexibility to play multiple infield spots and advanced metrics validating his offensive profile. If he earns regular playing time and replicates his minor-league production at the MLB level, his combination of run creation and power could well put him in the Rookie of the Year conversation.
